Each index described under the Credit Suisse Index Framework - Listed Markets (the “Framework”, and each such index, an “Index”) is documented by two separate master sections, which together constitute the “Index Operating Manual” for such Index. This Framework supersedes the previous Credit Suisse Commodity Index Framework; and references in any other document to such previous Framework shall be deemed to be a reference to this Framework and to the relevant Sections herein. The Framework is updated from time to time, whereby such updated version shall supersede prior ones. The latest Framework document is published on the Credit Suisse Websites (further details in section Index Publication herein). The Core Index Methodology is a common document to

all Indexes designed in the Framework. It provides an overall description of the Framework, describes the meaning of Key Index Terms, specifies the Calculation Engine referenced by the Index and provides definitions for these terms and notions used throughout the documentation. This section proposes an in-depth technical description of the calculations performed for all Indices under the Framework, regardless of the specific static data associated with each version of the Index.

The Index Parameters section provides specific details regarding parameters used for a particular version of an Index and the selected Calculation Engine in use for such index, and where applicable supersedes generic definitions given herein.

Disclaimers and Legal Considerations This disclaimer extends to CSi, its affiliates or its designate in any of its capacities as Index Sponsor, Index Calculation Agent, owner of the index methodology and its constitution of the Index Advisory Committee and Index Approval Committee, and any reference to CSi shall also mean a reference to its affiliates or designates in any such capacity. This document is published by CSi. CSi is authorised by the Prudential Regulation Authority (“PRA”) and regulated by the Financial Conduct Authority (“FCA”) and the PRA. Notwithstanding that CSi is so authorised and regulated, the rules of neither the PRA nor the FCA are incorporated into this document. The Index Sponsor and the Index Calculation Agent may be the same entity and the members of the Index Approval Committee and Index Advisory Committees may be employed by Credit Suisse AG and CSi or its affiliate may be the issuer of the Investment Products. CSi and its affiliates may, therefore, in each of its capacities face a conflict in its obligations carrying out such role with investors in the Investment Products and may resolve such conflict in its own interests. Except as prohibited by applicable law and regulation, CSi as Index Sponsor or as Index Calculation Agent may delegate to an affiliate or a third party some or all of its functions and calculations in respect of the Index. This document is published for information purposes only and CSi expressly disclaims (to the fullest extent permitted by applicable law and except loss caused by gross negligence, fraud or willful default on the part of CSi or its affiliates) all warranties (express, statutory or implied) regarding this document, including but not limited to all warranties of merchantability, fitness for a particular purpose of use and all warranties arising from course of performance, course of dealing or usage of trade and their equivalents under applicable laws of any jurisdiction. CSi or its affiliates may offer securities or other financial products including the Investment Products, the return on which is linked to the performance of the Index. This document is not to be used or considered as an offer or solicitation to buy or subscribe for such financial products nor is it to be considered to be or to contain any advice or a recommendation with respect to such financial products. Before making an investment decision in relation to such financial products one should refer to the prospectus or other disclosure document relating to such financial products. Neither CSi nor any of its affiliates (including their respective officers, employees and delegates) shall be under any liability to any party on account of any loss suffered by such party (however such loss may have been incurred) in connection with anything done, determined, interpreted, amended or selected (or omitted to be done, determined or selected) by it in connection with the Index, unless such loss is caused by gross negligence, fraud or willful default on the part of CSi or any of its affiliates. Without prejudice to the generality of the foregoing and unless caused by gross negligence, fraud or willful default on the part of CS or any of its affiliates, neither CSi nor any of its affiliates shall be liable for any loss suffered by any party as a result of any determination, calculation, interpretation, amendment or selection it makes (or fails to make) in relation to the construction or the valuation of the Index and, once made, neither CSi nor any of its affiliates shall be under any obligation to revise any calculation, determination, amendment, interpretation and selection made by it for any reason. Neither CSi nor any of its affiliates makes any warranty or representation whatsoever, express or implied, as to the results to be obtained from the use of the Index, or as to the performance and/or the value thereof at any time (past, present or future). CSi as Index Sponsor (including its officers, employees and delegates) has no obligation and will not take into account the interests of any investors in transactions or securities linked in whole or in part to the Index when determining, composing or calculating such Index. The Index Operating Manual is proprietary to CSi. Neither CSi nor any of its affiliates shall be under any liability to any party on account of any loss suffered by such party, unless such loss is caused by

gross negligence, fraud or willful default on the part of CSi or any of its affiliates, in connection with any change in any such model, or determination or removal in respect of such model (or any omissions to make any such change, determination or removal). The performance of the Index will depend, inter alia, on the performance of the Index Components and the performance of the Index Allocation Model and CSi, therefore, makes no guarantee or representation of any kind in relation to the performance of the Index, the level of which may go down as well as up. Past performance of the Index is no guarantee of future performance. Certain indices may provide a leveraged return to their underlying components. Where an index provides a leveraged return, an investor in such index is exposed not only to any leveraged upside return on such underlying components but is also exposed to any leveraged downside return on such underlying components, hence such downside may be greater than the notional amount of the relevant investment, and such investor may lose more than its initial investment. CSi does not purport to be a source of information on market risks with respect to the underlyings in any Index Component. CSi as Index Sponsor or Index Calculation Agent does not warrant or guarantee the accuracy or timeliness of calculations of any Index value and does not warrant or guarantee the availability of an Index value on any particular date or at any particular time. Neither CSi nor any of its affiliates is under any obligation to monitor whether or not a Disruption Event has occurred and shall not be liable for any losses, unless caused by gross negligence, fraud or willful default on the part of CS or any of its affiliates, resulting from (i) any determination that a Disruption Event has occurred or has not occurred in relation to an Index Component in the Index, (ii) the timing relating to the determination that a Disruption Event has occurred in relation to an Index Component in the Index or (iii) any actions taken or not taken by CSi as a result of such determination that an Disruption Event has occurred. Unless otherwise specified, CSi as Index Calculation Agent shall make all calculations and as Index Sponsor shall make all determinations, amendments, interpretations and selections in respect of the Index. Neither CSi nor any of its affiliates (including their respective officers, employees and delegates) shall have any responsibility for good faith errors or omissions in its calculations, determinations, amendments, interpretations and selections as provided in the Index Operating Manual unless caused by gross negligence, fraud or willful default on the part of CSi or any of its affiliates. The calculations, determinations, amendments, interpretations and selections of CSi shall be made by it in accordance with the Index Operating Manual, acting in good faith but otherwise in its sole, absolute and unfettered discretion (having regard in each case to the criteria stipulated herein and (where relevant) on the basis of information provided to or obtained by employees or officers of CSi responsible for making the relevant calculations, determinations, amendments, interpretations and selections). For the avoidance of doubt, any calculations or determinations made by CSi under the Index Operating Manual on an estimated basis shall not be revised following the making of such calculation or determination. CSi as Index Sponsor may supplement, amend (in whole or in part), revise or withdraw the Index Operating Manual at any time if, among other things, the Index is no longer calculable under the Index Operating Manual. Such a supplement, amendment, revision or withdrawal may lead to a change in the way the Index is calculated or constructed. CSi may determine that a change to the Index Operating Manual is required to address an error, ambiguity or omission. Such changes, for example, may include changes to eligibility requirements or construction. More details as to the Index Sponsor’s ability to amend, revise or withdraw the Index Operating Manual are set out in Section 2.5 herein. All amendments to the Index Operating Manual by CSi as Index Sponsor are proposed by the Index Advisory Committee via its members. The proposed changes are approved or rejected by the Index Approval Committee and are documented in the Index Operating Manual. CSi as Index Calculation Agent will apply the Index Operating Manual in a reasonable manner and in doing so may rely upon various sources of market information.

No person may reproduce or disseminate the information contained in this document without the prior written consent of CSi as Index Sponsor. This document is not intended for distribution to, or use by any person in a jurisdiction where such distribution or use is prohibited by law or regulation. No one other than CSi is permitted to use the Index Operating Manual or any Index Value in connection with the writing, trading, marketing, or promotion of any financial instruments or products or to create any indices, without the express written consent of CSi. The Index Operating Manual and any non-contractual obligations arising out of or in connection with the Index Operating Manual shall be governed by and construed in accordance with English law. Potential Conflicts of Interest Trading and other transactions by CSi and/or its affiliates in the futures contracts comprising an Index and the underlying futures may affect the value of such Index, and there may be conflicts of interest between investors in such Index and CSi and/or its affiliates. Each Index is based on futures contracts as described in the Core Index Methodology. CSi and/or its affiliates actively trade futures contracts and options on futures contracts on these underlyings. CSi and/or its affiliates also actively enter into or trade and market securities, swaps, options, derivatives, and related instruments which are linked to the performance of these underlyings or are linked to the performance of the Index. CSi and/or its affiliates may underwrite or issue other securities or financial instruments indexed to the Index, and CSi or its affiliates may license the Index for publication or for use by unaffiliated third parties. These activities could present conflicts of interest and could affect the value of the Index. For instance, a market maker in a financial instrument linked to the performance of the Index may expect to hedge some or all of its position in that financial instrument. Purchase (or selling) activity in the futures contracts included in the Index in order to hedge the market maker’s position in the financial instrument may affect the market price of such futures contracts included in the Index, which in turn may affect the value of the Index. In addition, such hedging activity, if carried out a significant period of time prior to any applicable close of trading in the relevant contract or security, may result in a gain or loss being incurred by such market maker as the index value is typically linked to the closing price. As a result, this hedging activity may result in the market maker producing revenue additional to the fees included and identified in the relevant transaction terms. Except as required by applicable law and regulation, with respect to any of the activities described above, neither CSi nor its affiliates has any obligation to take the needs of any investors in the Index into consideration at any time. Investment Products CSi or its affiliates may offer securities or other financial products (“Investment Products”) the return on which is linked to the performance of an Index created using the Core Index Methodology. These Investment Products may include options, swaps, other over-the-counter derivatives, certificates and notes. The related Index was developed with the formation of such Investment Products and related hedging strategies as key commercial elements to its development. Accordingly, CSi’s approach to the Index has been, and any change to the Index will be, influenced by CSi’s objective of creating and maintaining a futures index that is suitable as an underlying for Investment Products.

Executive Summary - General Framework Characteristics Main Characteristics The Credit Suisse Index Framework - Listed Markets (“Framework”) is composed of three

Calculation Engines as defined in the following Sections: 6.1. Long-Only Forward/Futures based calculation methodology (the “Long-Only

Forward/Futures Calculation Engine”). The composition of an index is vertical (Index Components representing certain futures markets) and horizontal (Curve Segments). The Framework allows the inclusion of all Index Components defined in the Index Components Universe. The horizontal structure allows the decomposition of the forward curves per Curve Segments, where relevant,

6.2. Index of Indices calculation methodology (the “Index of Indices Calculation Engine”) 6.3. Generic Basket of Assets calculation methodology (the “Generic Basket of Assets

Calculation Engine”) The universe of Index Components The universe of Index Components (the “Index Component Universe”) is defined as a result of

the selection process run annually. To be eligible for inclusion, all potential Index Components must satisfy a series of criteria.

The Index Components are selected based on a list of technical primary criteria, such as exchange facility location, currency, etc.

The Index Components must also pass a number of liquidity thresholds, where liquidity is defined as a function of Average Open Interest (which represents the average of the open positions in a futures contract on the relevant exchange) and Average Daily Volume (which represents the daily average number of transactions relating to a futures contract on the relevant exchange).

Changes to the composition of the Index Component Universe are proposed by the Index Advisory Committee and approved by the Index Approval Committee,

From time to time, the Index Approval Committee can decide to exclude an Index Component from the Index Component Universe if it deems such action necessary. All such actions follow the recommendation of the Index Advisory Committee.

Index Approval and Advisory Committees Any amendments to the Core Index Methodology and/or Index Parameters documents are

proposed by the Index Advisory Committee via its members. The proposed changes are approved or rejected by the Index Approval Committee and are documented in the relevant Index Operating Manual.

Index documentation: structure of the Index Operating Manual Each Index described under the Framework is documented by two separate master sections: a

section A. called Core Index Methodology which is common to all Indices, and a Section B. called the “Index Parameters” which is specific to a given version of the Index calculation.

The Core Index Methodology provides an in-depth technical description of the calculations performed by all Indices under the Framework, regardless of the specifics of the Index. In addition, it describes the function of the Index Approval Committee and the meaning of Key Index Terms and provides definitions for terms and notions used throughout the documentation.

The section called Index Parameters provides parameters specific to an Index, and where applicable supersedes generic definitions given in the Core Index Methodology.

2. The Index Operating Manual, the Index Approval and

Index Advisory Committees

2.1. The Index Operating Manual Each Index described under the Framework is documented by two separate master sections: The Core Index Methodology is a common document to all Indices created under the

Framework. It provides an overall description of the Framework, describes the meaning of Key Index Terms and provides definitions for terms and notions used throughout the documentation. The section proposes an in-depth technical description of the calculations performed for all indices under the Framework, regardless of the specific static data associated with each version of the Index,

The Index Parameters section provides specific details regarding parameters used for a particular

version of an Index, and where applicable supersedes generic definitions given in the Core Index Methodology.

2.2. The Index Approval Committee CSi, as Index Sponsor has established an Index Approval Committee responsible for providing general governance over the issuance and maintenance of Credit Suisse’s proprietary indices in all Fixed Income asset classes. In such capacity, the Index Approval Committee is responsible for overseeing the determination of the Framework and making decisions on any amendments to the Index Operating Manual. Any amendment to the Index Operating Manual should be recommended by the specific Index Advisory Committee pertaining to such Index. The Index Approval Committee consists of members appointed by the Index Sponsor. The members are comprised of senior management within CSi and bring substantial experience and expertise in the financial and commodity markets. As the Index Approval Committee may from time to time be required to discuss matters that may be non-public and potentially material to the performance or value of an Index, or an investment in or referencing an Index, committee members must be of sufficient seniority and where necessary appropriately segregated from those carrying out activities in support of the relevant Index or that might be the cause of potential conflicts of interest as a result of holding such information. The Index Sponsor is responsible for appointing the chairman and secretary of the Index Approval Committee. Members of the Credit Suisse Legal and Compliance Department will be ex-officio members of the Index Approval Committee, acting as advisors without a vote. The Index Approval Committee holds meetings regularly throughout the year, typically monthly, to discuss the monitoring of the relevant Indices including managing any errors or policy breaches arising, the approval of new Indices, the termination of existing Indices and potential changes to existing Indices, each as proposed by the relevant Index Advisory Committee. Annually, the Index Approval Committee, in particular and where applicable, reviews the following parameters in conjunction with the proposals from the Index Advisory Committees: Designated Commodity Derivative Instruments. These instruments are obtained from the evaluation

of the curve liquidity performed by the Index Advisory Committees. This process evaluates the tradability of the Designated Commodity Derivatives Instruments (e.g. futures contract) to ensure that all contracts included in the Index Component Universe feature adequate tradability to be part of a particular version of the Index,

Physical Pricing Instruments in the case where the relevant exchange has announced that a new futures contract is to be introduced or an existing futures contract is to be removed,

The Index Approval Committee may potentially review all parameters and structure of the Framework. In addition to the regular meetings, the Index Approval Committee may convene for additional meetings at the request of an Index Advisory Committee (“Extraordinary Meetings”) to discuss potential Market Emergency events, Extraordinary Events or any other situation which the Index Advisory Committee may deem makes such a meeting necessary. The members of the Index Approval Committee (which are subject to change) are the persons listed in Table I. below, or, in the event of their unavailability, their alternate.

2.4. Index Sponsor The Index Sponsor shall be the final authority of the interpretation of this Index Operating Manual and retains the final authority as to the manner in which the Index is calculated and constructed. The Index Sponsor shall apply the Index Parameter in a reasonable manner, and in doing so may rely upon various sources of information (including Index prices and settlement and/or closing futures prices). 2.5. Amendment of the Index Operating Manual The Index Sponsor, upon consultation with the Index Approval Committee and the Index Advisory Committee, may supplement, amend (in whole or in part), revise or withdraw any sections of the Index Operating Manual or change any of the Index Components at any time, if (a) the Index is no longer calculable pursuant to this Index Operating Manual, (b) a change to the Index Operating Manual is required to address an error, ambiguity or omission and effect any change thereto and/or, (c) if the Index Sponsor determines that an Extraordinary Event has occurred; provided that any such supplement, amendment or revision or withdrawal from or to the Index Operating Manual or change to

Page 13

the Index Components will be consistent with the fundamental structure and objectives of the Index. All material changes shall be ratified by the Index Approval Committee. In addition, upon the occurrence of a Licence Disruption Event, the Index Sponsor may remove or replace each Affected Index Component from the Index and make such amendments to the Index Operating Manual, as it determines in good faith to be appropriate to account for such event. Such a supplement, amendment, revision or withdrawal may lead to a change in the way the Index is calculated or constructed. Such changes, for example, may include changes to eligibility requirements or construction as well as changes to the Core Index Methodology, and when necessary the termination of, or suspension or cessation of the publication of, the relevant Index.

“Extraordinary Event” means any of the following circumstances: (i) a change in trading volume, terms or listing of any futures contract underlying any Index

Component; or, (ii) a change in supply or demand of any commodity underlying any Index Component; or, (iii) a change in any applicable or other laws, regulations or decisions; or, (iv) a change in foreign exchange regimes; or, (v) any event that would materially prejudice the accuracy or transparency of the calculation of the

Index; or, (vi) an Underlying Commodity Index Component or Financial Index Component is delisted from the

relevant exchange or in the case of an Index Component which is an Excess Return Index, the sponsor of such index terminates, or ceases publication of, such index or the method of calculating a component of such index, or the level thereof, is changed in a material respect; or,

(vii) the occurrence of a Correlation Determination (as defined in the Correlation Process in Section 7 and the relevant Index Parameters), being an increase in concentration risk beyond the prescribed levels due to increased correlation between Index Components.

which, in the case of Extraordinary Events (i) to (iv), results, in the opinion of the Index Sponsor, in either the pricing of an Index Component ceasing to be representative of the pricing of the underlying commodity or commodities to which it relates, or the Index Component otherwise ceasing to be a suitable benchmark for the commodity or commodities to which it relates.

3. Commodity Liquidity Calculations 3.0. Introduction to Liquidity calculations in the Framework When liquidity data is required, the Framework offers a variety of methods and tools that can help enhance the tradability of the constructed indices. For example: In the Underlying Commodity Index Component Universe: we use a measure of Average Daily

Open Interest and Average Daily Volume as a way to monitor and help select members part of the framework,

An example of such methods is the following used in the CSCB weighting engine: we use liquidity data for the purpose of allocating weights to the Commodities sharing the same underlying commodity. Such as NY Harbor ULSD or Gasoil and the available Crude Oil contracts which are allocated petroleum/crude oil weights

In the forward curve weighting engine: we use liquidity data to weight Index Pricing Instruments within their associated Curve Segment as well as Curve Segments in the overall Curve Segment Index,

This section outlines a detailed calculation methodology for the following variables/quantities: WCM: Weight Calculation Month, WCP: Weight Calculation Period, OILW: Open Interest Liquidity Weights, VLW: Volume Liquidity Weights, CLW: Component Liquidity Weights, PDPLW: Physical Delivery Period Liquidity Weights, IPITW: Index Pricing Instrument Target Weights, CSTW: Curve Segment Target Weights. 3.1. Weight Calculation Month (WCM) If applicable, the Weight Calculation Month (WCM) is the month during which the Liquidity Component Weight and the Target investment Weights are calculated and is used as reference for the Weight Calculation Period. It is specified in the relevant Index Parameters. 3.2. Weight Calculation Period (WCP) We define the Weight Calculation Period (WCP) as the twelve months period ending in June immediately preceding the Weight Calculation Month (WCM)2. To take into account the specificities of certain Index Components or cater for certain index particularities, the Index Advisory Committee may make a recommendation in respect of the WCP to the Index Approval Committee at any Ordinary or Extraordinary Meeting. 3.3. Daily Open Interest (DOI) and Daily Volume (DV) For the purpose of the determination of Index Component absolute liquidity, we generally use the Framework steps (such as curve decomposition and Index Pricing Instrument (IPI) designation) as specified for calculation of the Credit Suisse Commodity Benchmark Index (CSCB). STEP 1. For each Index Business Day during the reference WCP, and for a given commodity contract, we construct the Index Pricing Instrument sequence as shown in Table I. below for the month associated with the Calculation Date (note that if such date is past the end of the theoretical roll period for this Index Component, we construct the sequence for the following month. For example,

2 : Prior to the WCM in 2010, the WCP ended in September.

3.7. Component Liquidity Weights (CLW) Component Liquidity Weights (CLW) are calculated annually during the Weight Calculation Month (WCM). They are defined as part of the general weighting mechanism and are calculated for each Underlying Commodity Index Component. They are the result of appreciation of relative Underlying Commodity Index Component liquidity. To calculate CLW, we blend OILW and VLW and for each Curve Segment. The aggregate Liquidity is derived from Total Open Interest and Total Volume. To perform the blend, we use an Open Interest to Volume ratio of 75/25%.

3.8. Physical Delivery Period Liquidity Weights (PDPLW) Physical Delivery Period Liquidity Weights are calculated annually during the Weight Calculation Month (WCM) defined above. The Weight Calculation Month is defined as the month during which the new Target Investment Weights are made available for the subsequent re-weighting period. The PDPLW are defined as part of the general curve segment weighting mechanism. They are the weights assigned to each of the j Index Pricing Instruments (IPI) defining the tradable forward curve and are the result of the appreciation of relative liquidity along the Index Components forward curve. They are calculated via the following steps: STEP 1. We perform STEP 1 and STEP 2 of the sequence featured in Section 3.3. above. The curve decomposition as well as intermediate results are shown in Table V. below. STEP 2. For each position in the curve, we calculate the Daily Percentage liquidity data: Daily Percentage Open Interest (DPOI), and Daily Percentage Volume (DPV).

3.11. Specific liquidity evaluation procedures for non-standard commodity contracts 3.11.1. London Metal Exchange Before we can use the official open interest and daily volume data made available by the exchange on LME Physical Metals forward contracts, we must first reformat the data to fit the general contract framework common to most Futures contracts. Ignoring all the non 3rd Wednesday “prompt dates” would have the adverse consequence of incorrectly increasing long dated LME metals exposure. To perform this task we “bucket” all available “non 3rd Wednesday“ Open Interest or Volume data for a given month. We then aggregate the data with the “3rd Wednesday prompt” to form the aggregated monthly data (Open Interest or Volume). The data produced is then used in the liquidity evaluation processes above. 3.11.2. ICE Coal: Monthly Equivalent Contract Allocation (MECA) procedure The three Designated Commodity Derivatives Instruments for ICE Coal futures Contracts are Monthly, Quarterly and Calendar Futures contracts. The three contracts trade simultaneously on a given trading date. Prior 2010, to perform the forward curve liquidity evaluation process for ICE Coal, CS remapped any obtained Quarterly and Calendar futures contracts data into adequate equivalent Monthly contract data3. The results are then added to the standard monthly figures to be used in the liquidity evaluation processes above.

3 : The ICE Open Interest reporting methodology seemed to have changed on or around the 21th Nov 2008, from this date onwards all open interest data is automatically mapped on the equivalent Monthly Futures Contract.

From 2010 onwards, the Monthly Equivalent Contract Allocation (MECA) procedure has been automatically performed by the exchange, and as a result, the data featured by the various data vendors (Bloomberg, Reuters, etc) for Quarterly and Calendar futures tends to be empty. For the purpose of obtaining Volume data, we perform the MECA procedure in order to obtain a monthly contract equivalent Volume data. The data produced in this process can later be re-aggregated for the purpose of evaluating the liquidity conditions of Quarterly and Calendar contracts.

Each of the Underlying Commodity Index Component Universe and the Financial Index Component Universe is defined as a result of the selection process run annually, and at such other times as necessary due to changes in market conditions or in response to client interest. To be eligible for inclusion, the following considerations will be taken into account.

4.1. Selection criteria for the Underlying Commodity Index Component Universe 4.1.0. General considerations regarding physical properties of the commodity An Underlying Commodity Index Component is made eligible for inclusion in the Framework if the underlying instrument is a single, storable physical commodity, i.e. such instrument is not a mean of transport, a certificate or a tradable right. Exceptions can be made to allow the inclusion of other significant futures contracts as such markets develop. 4.1.1. Exchange facility geographical location In general, Underlying Commodity Index Components must be traded on primary exchanges located and subject to regulation in the United States of America, member countries of the European Union or the United Kingdom. However commodities traded on other exchanges are also considered on a case by case basis. 4.1.2. Contract currency All Underlying Commodity Index Components must be traded in US Dollars (USD), British Pounds (GBP) or Euros (EUR). However commodities traded in other currencies are also considered on a case by case basis. 4.1.3. Pricing transparency All Underlying Commodity Index Components must feature an official daily “Settlement Price”, or official “Mark to Market” mechanism by a financially independent, and non-trading entity such as: an exchange, a board of trade, an independent financial data publisher, a recognised rating agency (e.g. Standard & Poor’s, Moody’s, Fitch Ratings, etc.), a government agency, or any other source deemed acceptable by the Index Approval Committee. 4.1.4. Type of delivery mechanism An Underlying Commodity Index Component must be supported by a physical delivery process such as traditional physically delivered futures contracts or physical forwards. When an instrument features a cash settlement procedure, it must demonstrate transparency acceptable to the Index Approval Committee. For example, when the futures contract is settled against a physical or cash index, the final settlement mechanism should adequately represent the physical market on the last day of trading.

4.1.5. Length of trading history Commodities selected for inclusion ideally will have a reasonable period of trading history, preferably in excess of one year, prior to inclusion in the Framework. Exceptions will be made as deemed necessary by the Index Approval Committee. For example, this may be necessary when a new contract is launched by an exchange in substitution of another preexisting contract, where delivery specification changes require a new contract to be launched to replace a preexisting contract after a period of overlapping trading. 4.1.6. Data availability and transparency Commodities selected for inclusion ideally will have readily available data, both on a real time and historical basis. 4.1.7. Inclusion in selected commodity Index benchmarks An Underlying Commodity Index Component included in the following major index benchmarks shall be available for inclusion in the Framework, S&P GSCI©, Bloomberg Commodity index

Note that the inclusion of an Underlying Commodity Index Component in the Underlying Commodity Index Component Universe does not automatically constitute its inclusion in an Index supported by the Framework. 4.1.8. Market recognition The commodities included in the Framework are determined annually based on several criteria. The objective is to incorporate as many physical commodity futures as possible while maintaining the liquidity and robustness that an institutional portfolio would require for replication of an Index supported by the Framework. A further important criteria for inclusion is the market recognition a particular contract has achieved amongst major market participants such as institutional investors, banks and corporations. The Index Approval Committee shall consider adding any additional commodities if required or requested, where appropriate, on a case by case basis. 4.1.9. Liquidity To ensure that any commodities to be included in the Framework are sufficiently liquid, the Index Approval Committee will consider the average volume and open interest of a commodity prior to accepting it as a member of the Framework. A commodity should meet the following minimum liquidity requirements in order to be included in the Framework: As measured over the prior twelve months, the commodity should have A minimum of $200 million Average Daily Open Interest (as measured by the methodology

set forth in Section A.3.5. Average Daily Open Interest (ADOI) and Average Daily Volume (ADV)). The maintenance threshold, which applies in subsequent years following inclusion, is fixed at $150 million, and,

A minimum of $40 million Average Daily Volume (as measured by the methodology set forth in Section A.3.5. Average Daily Open Interest (ADOI) and Average Daily Volume (ADV)). The maintenance threshold, which applies in subsequent years following inclusion, is fixed at $25 million.

The Index Approval Committee will consider exceptions to this rule on a case by case basis. The current exceptions are Coal API #2, Random Lumber, Rough Rice, Oats, Orange Juice, TOCOM Rubber, TOCOM Silver and TOCOM Palladium.

4.3. Selection criteria for the Financial Index Component Universe 4.3.1. Contract currency Financial Index Components are expected to be traded in the currency of a G10 nation. However contracts traded in other currencies are also considered on a case by case basis. 4.3.2. Pricing transparency All Financial Index Components must feature an official daily “Settlement Price”, or official “Mark to Market” mechanism by a financially independent, and non-trading entity such as: an exchange, a board of trade, an independent financial data publisher, a recognised rating agency (e.g. Standard & Poor’s, Moody’s, Fitch Ratings, etc.), a government agency, or any other source deemed acceptable by the Index Approval Committee. 4.3.3.

4.3.5. Market recognition The Financial Index Components included in the Framework are determined annually based on several criteria. The objective is to incorporate as many financial instruments as possible while maintaining the liquidity and robustness that an institutional portfolio would require for replication of an Index supported by the Framework. A further important criteria for inclusion is the market recognition a particular contract has achieved amongst major market participants such as institutional investors, banks and corporations. The Index Approval Committee shall consider adding any additional components if required or requested, where appropriate, on a case by case basis. 4.3.6. Liquidity To ensure that any Financial Index Components to be included in the Framework are sufficiently liquid, the Index Approval Committee will consider the average volume and open interest of the instrument prior to accepting it as a member of the Framework. A Financial Index Component should meet the following minimum liquidity requirements in order to be included in the Framework: As measured over the prior twelve months, the component should have A minimum of $5 billion Average Daily Open Interest. The maintenance threshold, which

applies in subsequent years following inclusion, is fixed at $4 billion, and, A minimum of $1 billion Average Daily Volume. The maintenance threshold, which applies in

subsequent years following inclusion, is fixed at $750 million. The Index Approval Committee will consider exceptions to this rule on a case by case basis. The current exception is the CME New Zealand Dollar future. The inclusion thresholds applied in the Framework may be different than the inclusion thresholds defined for a specific Index, which may for example feature higher levels of liquidity thresholds.

5. Disruption Events and Market Emergency

5.1. Index Disruption Events In the determination of the Index Sponsor, the following events are each referred to as “Index Disruption Events”: Any suspension of or limitation imposed on trading by any stock exchange, futures exchange or

other exchange (each an “Exchange”) on which any futures contract referenced (albeit notionally) as an underlying of an Index Component is quoted whether by reason of movements in price exceeding limits permitted by any relevant Exchange or otherwise, which, taking into account all relevant Exchanges, represents a material percentage amount in aggregate weight of the relevant Index Component, as determined by the Index Sponsor;

Any event that disrupts or impairs (as determined by the Index Sponsor) the ability of market participants in general to effect transactions in, or obtain market values for any futures contract referenced (albeit notionally) as an underlying of an Index Component, which represents a material percentage amount in aggregate weight of the relevant Index Component, as determined by the Index Sponsor;

An event resulting in a breakdown in any means of communication or a procedure normally used to enable the determination of the Index Level, or any other event, in the determination of the Index Sponsor, that prevents the prompt or accurate determination of the Index Level, or the Index Sponsor concludes that as a consequence of any event, the last reported Index Level should not be relied upon;

The Index Sponsor reasonably believes that the Core Index Methodology has determined an Index Level, or produced any other determination, that cannot be relied upon;

The failure, suspension or postponement of any calculation within the Core Index Methodology in respect of any Index Business Day;

The Index Sponsor determines that the Index Allocation Model has provided a signal that the Index Sponsor reasonably believes cannot be relied upon;

The failure, suspension or postponement of the Index Allocation Model to provide a signal to the Index Calculation Agent on the relevant day;

The Index Sponsor reasonably believes that the Index Operating Manual includes an error, omission or ambiguity;

The ability of the Index Calculation Agent to determine the market value of an underlying index or related futures contract for the purposes of calculating the Index is adversely effected;

the Index Sponsor determines there has been a Change in Law where “Change in Law” means (A) the adoption of or any change in applicable law or regulation (including, without limitation, any tax law) or (B) the promulgation of or any change in the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law or regulation (including action taken by a taxing authority) which, in the determination of the Index Calculation Agent (in its sole discretion) would (i) make it illegal for the Index Calculation Agent to perform its duties under these Index Rules or in respect of its hedging arrangements or (ii) will cause the Index Calculation Agent to incur a materially increased cost in performing its obligations under this Index Operating Manual or in respect of its hedging arrangements (including, without limitation, due to any increase in tax liability, decrease in tax benefit or other adverse effect on its tax position); or

A failure, suspension or postponement in the reporting or publishing of the value of any underlying index or related futures contract as regularly scheduled, or any event that prevents the value of an underlying index or related future so published from being received by the people to whom it is published, whereby such event is, in the determination of the Index Calculation Agent, material; or

Any circumstances where, although the value of an underlying index or related futures contract is published, the Index Calculation Agent determines that such value is not accurate or that any transaction in respect of the underlying index or related futures contract could not be transacted at such value or with a cash consideration in full, and to be received as regularly scheduled.

5.1.1. Disrupted Valuation Days inheritance: Disruption Groups In certain circumstances, the occurrence of a Disrupted Valuation Day in respect of one Index Component will have an effect on the trading of the futures contracts underlying other Index Components. For the purposes of determining the effect of a Disrupted Valuation Day on the Roll Period, such Index Components are grouped together in a “Disruption Group”. All Index Components that belong to a Disruption Group containing an Index Component in respect of which a Disrupted Valuation Date has occurred are deemed to be Disrupted Index Components for the purposes of section 5.1, such that the Roll Weights for each Index Component of the Disruption Group will remain identical to the values they had on the Index Business Day immediately preceding the Disrupted Valuation Day. Disruption Groups pertaining to a specific Index are specified in the relevant Index Parameters. 5.2. Fall-Back Provisions 5.2.1. Commodity Indices Where, in the determination of the Index Sponsor, either (a) an Index Disruption Event (as defined in section A.5.1.) has occurred and subsists in respect of any Index Business Day or (b) on any Index Business Day any exchange on which any commodity futures contract referenced (albeit notionally) as an underlying of an Index Component is quoted is not scheduled to be open, and is not open, for trading for its regular trading session (each such Index Business Day, a “Disrupted Valuation Day”), the Index Sponsor may in respect of such Disrupted Valuation Day (i) determine the Index Level on the basis of estimated or adjusted data and publish an estimated level of the Index, (ii) delay, suspend or terminate the publication of the index, and/or (iii) following such Disrupted Valuation Day(s), adjust the price or level of any Index Component within the Index or, any other factor or variable involved in the calculation of the Index it deems necessary, in its reasonable opinion, to account for the relevant event described above. If any Index Business Day during the Roll Period is a Disrupted Valuation Day, each Index Component which was affected by such Commodity Disruption Event or such scheduled closure (a “Disrupted Index Component”) is not rebalanced on that day. In addition, the Roll Weights referred to as RWm

c,w

for each Disrupted Index Component will remain identical to the values they had on the Index Business Day immediately preceding the Disrupted Valuation Day (such that, if such Index Business Day is the first day of the Roll Period as well as the SDCD, RWm

c,w in respect of such Index Business Day shall have the value it would have if such Index Business Day was not a roll day). Each Disrupted Index Component is rebalanced on the next Index Business Day on which there is not a Disruption Event in relation to the relevant Index Component. If the three (3) following Index Business Days are Disrupted Valuation Days (referred to as an “Extended Disruption Period”), the Index Approval Committee, in conjunction with the Index Advisory Committee, may determine, in good faith and in a reasonable commercial manner, on the earlier of (a) three Index Business Days following the initial Disrupted Valuation Day or (b) the Last Trading Day of the relevant Index Component, the relevant IPIPm

c,CS,j allocated to the Index Component c, Curve Segment CS and Index Pricing Instrument j for each such Disrupted Index Component in respect of the Index Business Day following the Extended Disruption Period.

5.2.2. Interest Rate Indices

Where, in the determination of the Index Sponsor, an Index Disruption Event has occurred or is existing and subsisting in respect of any Index Business Day (a “Disrupted Valuation Day”), the Index Sponsor may in respect of such Disrupted Valuation Day (i) delay, suspend or terminate the calculation and publication of the Index Value and/or (ii) determine the Index Value on the basis of estimated or adjusted data and publish an estimated level of the Index Value and/or, (iii) take any action, including but not limited to, using the most recent signals received from the Index Allocation

[email protected]



Page 33

Model, designating alternative price sources, and/or alternative exchange rate calculations, adjusting swap term conventions (if applicable), reconstituting the Index (e.g., a change in weights and/or FX fixings).

If the Index Rebalancing Date is a Disrupted Valuation Day, each Index Component which was affected by such Disruption Event or such scheduled closure (a “Disrupted Index Component”) is not rebalanced on that day.

5.2.3. Foreign Exchange Indices Where, in the determination of the Index Sponsor, an Index Disruption Event (as defined below) has occurred or exists and subsists in respect of any Index Business Day (each such Index Business Day, a “Disrupted Valuation Day”), the Index Sponsor may in respect of such Disrupted Valuation Day (i) determine the Index Value on the basis of estimated or adjusted data and publish an estimated level of the Index and/or (ii) following such Disrupted Valuation Day(s), adjust the price or level of any Index Component within the Index or, any other factor or variable involved in the calculation of the Index it deems necessary, in its reasonable opinion, to account for the relevant event described above and/or (iii) use a designated alternative price source for a currency and/or (iv) use a designated alternative price calculation method to compute rates and/or (v) delay, suspend or terminate the publication of the index. If the Index Rebalancing Date is a Disrupted Valuation Day, each Index Component which was affected by such Disruption Event or such scheduled closure (a “Disrupted Index Component”) is not rebalanced on that day. 5.3. Market Emergency

The Index Approval Committee, in consultation with the Index Advisory Committee, will declare a Market Emergency when circumstances are deemed to have a material effect on the tradability of an Index. In such circumstances, the Index Approval Committee may need to take immediate actions it deems appropriate to ensure that the integrity of the Index is preserved, including when necessary the suspension or cessation of the publication of the relevant Index. 5.4. Consultation with External Stakeholders Unless explicitly stated in the relevant Index Operating Manual, no consultation with external stakeholders is envisaged.

6. Index Calculation methodologies

6.1. Long-Only Forward/Futures based calculation methodology 6.1.1. Basic definitions The definitions and descriptions included in this section are applied in the relevant Index calculation as necessary. Any terms or definitions may be specified further in the relevant Index Parameter, which may supersede such definitions herein, or might not be required for the purposes of the specific Index calculation (for example, the concepts of Curve Segment, IPI Designation and Physical Delivery Periods may not be applicable to Indices using Index Components from the Financial Index Universe). 6.1.1.0. Technical summary In this section we introduce the Long-Only Forward/Futures Calculation Engine. We also define the following concepts: Physical Delivery Period: For a given commodity, we define a Physical Delivery Period as each

calendar month in the following 3 years period, Physical Pricing Instruments: For each such monthly Physical Delivery Period, we assign a

Physical Pricing Instrument (PPI) as the futures contract which may be used in Physical commodity transactions for pricing purposes,

Curve Segments: We decompose of the forward price curve into successive segments (“Curve Segment”). For a given version of the Index, the specific decomposition of the forward curve is defined in relevant Index Parameters,

Designated Commodity Derivatives Instruments: For a given commodity (Index Component) and Curve Segment, we define Designated Commodity Derivatives Instruments as the Futures contracts that can be referenced in a Curve Segment. These are defined for each Index Component in relevant Index Parameters,

Index Pricing Instrument: We assign an Index Pricing Instrument to each Physical Pricing Instrument, to take into account liquidity and tradability/availability of futures contracts and derivatives instruments. All Index Pricing Instruments are required to be Designated Commodity Derivative Instruments (DCDI) for the relevant commodity and Curve Segment.

Indices: For each Index component, we calculated one Index per Curve Segment (each a “Curve Segment Index”) and one Index for the entire tradable curve (each a “Forward Curve Index”).

6.1.1.1. Physical Pricing Period (PPP), Physical Pricing Instruments (PPI) and Designated Commodity Derivative Instruments 6.1.1.1.1. Physical Pricing Period (PPP) and Physical Pricing Instruments (PPI) For each Underlying Commodity Index Component and each Physical Delivery Period, the Physical Pricing Instruments (PPI) are defined as the Futures contract typically used in reference to the pricing of physical transactions. These primarily consist of monthly Futures contracts, but for some Index Components, quarterly Futures contracts may also be used (see Table I.b. Physical Pricing Instruments (Quarterly Contracts) below). In general, the PPIs are the nearby month contract associated with the relevant month. The exception to this is for commodities where a nearby month contract doesn’t exist for each consecutive month in which case the closest available nearby month contract is used. For each Index Component, the PPIs are defined, at inception, using the commodities code stated below. Any subsequent changes to the PPIs as a result of the introduction of a new futures contract or the removal of an existing futures contract will be determined by the Index Approval Committee as outlined in the Section A.2. The Index Operating Manual, the Index Approval and Advisory Committees.

6.1.1.1.2. Designated Commodity Derivative Instruments (DCDI) For each Underlying Commodity Index Component and each Curve Segment, a list of valid contract codes is defined in relevant Index Parameters. The Designated Commodity Derivative Instruments are reviewed by the Index Approval Committee annually, in conjunction with the Index Advisory Committee, as outlined in Section A.2. The Index Operating manual, The Index Approval and Advisory Committees. 6.1.1.2. Index Pricing Instruments (IPI) The Index Pricing Instruments are determined via the two methodologies using the Designated Commodity Derivative Instruments (DCDI) and the Physical Pricing Instruments (PPI) defined in the relevant Index Parameters. 6.1.1.2.1. Standard IPI Designation Procedure Using the Designated Commodity Derivative Instruments (DCDI), we associate an IPI (in the form of contract codes) for each Physical Delivery Period (PDP) and each Index Component. For each Underlying Commodity Index Component, the Index Pricing Instruments are set equal to the PPI’s except when: The PPI is not a Designated Commodity Derivative Instrument, The difference between the PPI’s First Notice Day and the theoretical end of the Roll Period is

less than the First Notice Day Clearance Period defined in the relevant Index Parameters. The difference between the PPI’s Last Trading Day and the theoretical end of the Roll Period is

less than the Last Trading Day Clearance Period defined in the relevant Index Parameters. In these cases, the Index Pricing Instrument is set to the Designated Commodity Derivative Instrument associated with the following Physical Delivery Period. Note that in the standard IPI designation procedure, the IPI is always equal to the non-adjusted IPI. Table II. Standard IPI designation procedure for a {3, 3, 6, 12, 12} forward curve structure

6.1.1.2.2. Alternative IPI designation procedure When the Alternative IPI designation procedure is in use, the IPI is set to the non-adjusted IPI associated with the following Physical Pricing Instrument (PPI) if the non-adjusted IPI is different to the PPI for the first Physical Delivery Period only. In the example Table III below, for the Reference Period of December, the February non-adjusted IPI (in red) is G. The February IPI (in green) set equal to H because the non-adjusted IPI of January (the first PDP) is not equal to the January PPI. Table III.

6.1.1.3. Decomposition of the Commodity Forward Curve in Curve Segments (CS) We decompose the commodity forward price curve into Curve Segments (CS) using the pre-defined Physical Delivery Segments defined in the relevant Index Parameters. For a given Underlying Commodity Index Component, a Curve Segment Index will only exist if the Curve Segment has been assigned Designated Commodity Derivative Instruments. The structure of the forward price curve is described as the number of monthly Physical Delivery Period comprising each segment. For example, the notation {1, 2, 3, 6, 12, 12} means that the forward curves of all commodities in the Index are decomposed in the following way: The first segment (called 1F or more generically the PROMPT segment) is made of a single

Physical Delivery Period, The second segment, also called 2x3F, covers two Physical Delivery Periods, The third segment, called 4x6F, has three Physical Delivery Periods, The fourth segment, called 7x12F, has six Physical Delivery Periods, The subsequent two segments called 13x24F and 25x36F cover respectively twelve Physical

Delivery Periods.

6.1.1.4. The Roll Period

The Roll Period represents the period from and including the First Roll Date (FRD) to and including Last Roll Date (LRD). During the Roll Period, the Index transfers positions from the Curve Segment Value (CSV) defined for month m, to the CSV defined for the following month (denoted as m+1) (as described in further detail in Section 6.1.1.5. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date). Both the Start and End of the Roll Period are defined in term of the number of Index Business Days from the last Index Business Day of the month prior to the Reference Period m. For example, [+1(m)/+9(m)] means that the roll starts on the 1st Index Business Day and ends on the 9th Index Business Day of the Reference Period. 6.1.1.4.1 The Static Data Calculation Date (SDCD)

We define the Static Data Calculation Date (SDCD) as the date, specified in the relevant Index Parameters, on which the Static Data are calculated for the Reference Period m. For indices calculated under the Long-Only Forward/Futures Calculation Engine, on the Static Data Calculation Date we calculate the Nominal Weights and Nominal Weights Factors according to the particular specifications as detailed in the relevant Index Parameters. 6.1.1.4.2 The definition of Roll Weights (RW) for the Price Return Index

We have defined the Roll Period as a range of Index Business Days over which a transfer of position may take place. For example, if the Roll Period was defined as the 1st to the 9th Index Business Day of the Calculation Period, the Price Return Index starts to reference the CSV defined for Reference Period m+1 on the 1st Index Business Day of the month, and hence when/if the transfer of positions takes place over consecutive Index Business Days, the rate of positions transfer takes place at the roll rate RR defined by:

).1.1.6.( 1

1aA

FRDLRDRR

FRD the First Roll Date in the Roll Period, LRD the Last Roll Date in the Roll Period.

Note that roll dates are not necessarily consecutive Index Business Days and can follow a customised schedule. The Roll Period for a particular version of the Index is defined in the relevant Index Parameters. During the Roll Period, in the absence of a Disrupted Valuation Day, the values taken by the Roll Weights can be as shown in Table V. below. Table V.

In order to mitigate the effect of Disrupted Valuation Days occurring during the Roll Period and prevent any discontinuity from affecting the Excess Return Index, the Roll Period of the Excess Return Index is delayed by one Index Business Day compared to the Roll Period of the Price Return Index, i.e. the values taken by RWm

c,t on a Calculation Date are equal to the Roll Weight used by the Price Return Index on the immediately preceding Calculation Date, hence the notation RWm

6.1.1.4.4. The values of Roll Weights (RW) during Disrupted Valuation Days

In the following two sections, we define the procedures governing the calculation of the Index when a Disrupted Valuation Day takes place during a Roll Period. We define both the “Standard Roll” and the “Extended Roll” methodology. Disrupted Valuation Days that occur outside the Roll Period do not affect the proportion or futures contract positions maintained to hedge the dollar exposure in the Index and so no adjustment to the RW schedule is necessary. 6.1.1.4.4.1. Standard Roll methodology If a Disrupted Valuation Day occurs during the Roll Period, the RW associated with the Price Return Index on that day remains unchanged when compared to its value on the previous Index Business Day which was not a Disrupted Valuation Day in relation to the relevant Index Component. The RW on the next Index Business Day which is not a Disrupted Valuation Day is updated so that it reflects the RW which would have existed on such Index Business Day had the relevant Disrupted Valuation Days not occurred. Unless a Disrupted Valuation Day occurs on the last day of the Roll Period, the length of the Roll Period is unaffected (See Table VII below).

If a Disrupted Valuation Day occurs on the last day of the Roll Period, the length of the Roll Period is extended until the transfer of positions is completed, subject to the occurrence of further Disrupted Valuation Days, provided that if the Roll Period continues until the Last Possible Roll Date (as defined in paragraph 6.1.1.4.4.2. (Extended Roll methodology) below), and the Last Possible Roll Date is also a Disrupted Valuation Day, the Index Sponsor may determine, in good faith and in a reasonable commercial manner, the Index Pricing Instrument Price (IPIP) for the relevant Index Component (See Table VIIIa below).

6.1.1.5. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date To facilitate the notations and calculations, we further define the following concepts: The Calculation Date: any Index Business Day for which an Index Closing Level is published, The Static Data Calculation Date (SDCD): an Index Business Day on or prior to the start of the

Roll Period, specified in the relevant Index Parameters, on which the calculation of the Static Data is performed,

The Calculation Period: in respect of a Static Data Calculation Date the monthly period from and including such Static Data Calculation Date, to but excluding the immediately following Static Data Calculation Date,

The Reference Period: in respect of a Calculation Date t, the month (denoted as m) determining the relevant Index Pricing Instruments (or structure of the forward curve) and defined as the calendar month in which falls the Last Roll Date in respect of the Calculation Period in which the Calculation Date t occurs (see Section 6.1.1.4. The Roll Period).

As such, formula A.6.1.2. above is altered as further detailed in Appendix A herein. 6.1.1.6.1. Index Pricing Instrument designation methodologies The Framework supports two distinct IPI designation methodologies for Underlying Commodity Index Components to reflect the differing calculation methodologies around exchange holidays and non Index Business Days: the “Index Schedule” method: the method ignores Index Components’ open exchange days for

non Index Business Days: this is the default methodology for the Long-Only Forward/Futures Calculation Engine, and it is used, for example, in the calculation of the CSCB and the BCOMSM Index,

the “Index Component Exchange Schedule” method: the method takes into account open exchange days on non Index Business Days: this methodology is used in the calculation of the S&P GSCI™.

Calculation of Nominal Weight Factors (NWF) The expression of Nominal Weight Factors is a function of whether the month m+1 is a forward curve rebalancing month as defined in the relevant Index Parameters. If m is a Curve Rebalancing Month (as defined in the relevant Index Parameters), the Nominal Weight Factors (NWF) will be calculated to reflect the Nominal Weights for the period m+1 and also potentially the new Curve Segment Target Weights (CSTW) for that period. If m is not a Curve Rebalancing Month, the Nominal Weight Factors (NWF) will be calculated to reflect the Nominal Weights for the period m+1 and the current Curve Segment Target Weights (CSTW) for that period. The Forward Curve rebalancing process (affecting the weight distribution of Curve Segment dollar weight) is therefore independent from the rebalancing affecting Index Component dollar weights as potential changes on Target Investment Weights (reflecting changes in Nominal Weights) for the period m+1 are factored in, but the dollar weight allocation for Curve Segment can remain unaffected. 6.1.1.9.1.

“dayst” is the number of calendar days from the Calculation Date immediately preceding the Calculation Date t, to the Calculation Date t.

6.1.4.3. Calculation of the Total Return Index The framework supports two distinct calculation methodologies for the Total Return Index, to reflect the differing treatment of collateral yield for non-Index Business Days: the “Daily Equivalent Rate method”: for two consecutive Index Business Days, the method

calculates an equivalent rate, the Daily Collateral Yield (DCYCCYdays,t) for the calendar period (days

is 1). This rate is then added to the Excess Return obtained for the Calculation Date t and compounded with the Total Return Index level obtained on t-1,

the “Compounding method”: for two consecutive Index Business Days, the method compounds the Daily Collateral Yield calculated for one day (DCYCCY

1,t) for each such non-Index Business Day with the Total Return obtained on Calculation Date t for one calendar day.

For a given Index, the Total Return Index calculation method is defined in the relevant Index Parameters. 6.1.4.3.1.

6.2. Index of Indices calculation methodology In this section we introduce the Index of Indices Calculation Engine. This engine, which can utilise long and short positions in underlying indices as Index Components, is compatible with all Excess Return indices supported by the Long-Only Forward/Futures Calculation Engine described in Section A.6.1. Long-Only Forward/Futures based calculation methodology.

6.2.1. Basic definitions 6.2.1.1. The Roll Period

The Roll Period represents the period from and including the First Roll Date (FRD) to and including Last Roll Date (LRD). During the Roll Period, the Index transfers positions relating to the Static Data (as defined in paragraph 6.2.1.1.1 The Static Data Calculation Date (SDCD) below) for the previous Reference Period (denoted as m-1), to the positions relating to the Static Data relating to the current Reference Period (denoted as m) (as described in further detail in Section 6.2.1.2. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date). Both the Start and End of the Roll Period are defined in term of the number of Index Business Days from the Static Data Calculation Date of the relevant Calculation Period. For example, [+1(m)/+9(m)] means that the roll starts on the 1st Index Business Day and ends on the 9th Index Business Day of the Calculation Period. 6.2.1.1.1 The Static Data Calculation Date (SDCD)

We define the Static Data Calculation Date (SDCD) as the date, specified in the relevant Index Parameters, on which the Static Data are calculated for the Reference Period m. For indices calculated under the Index of Indices Calculation Engine, on the Static Data Calculation Date we calculate the Signal (S) and the Nominal Weights (NW) according to the particular specifications as detailed in the relevant Index Parameters. 6.2.1.1.2 The definition of Roll Weights (RW) and Signal Roll Weight (SRW) for the Price Return Index

We define the Roll Period as a range of Index Business Days over which the transfer of positions defined for the Reference Period m-1 to the Reference Period m takes place. The Roll Rate (RR) is the frequency at which positions are transferred over the Roll Period. For example, if the Roll Period was defined as the 3rd to the 5th Index Business Day of the Calculation Period, the Price Return Index starts to reference the Static Data defined for the relevant Reference Period on the 3rd Index Business Day of the Calculation Period.

The Roll Period for a given Index is defined in the relevant Index Parameters.

6.2.1.1.3. The definition of Roll Weights (RW) and Signal Roll Weight (SRW) for the Excess Return Index

The Roll Period of the Excess Return Index is delayed by one Index Business Day compared to the Roll Period of the Price Return Index, i.e. the values taken by RWm

c,t (resp. SRWmc,t) on a Calculation

Date are equal to the Roll Weight (resp. Signal Roll Weight) used by the Price Return Index on the immediately preceding Calculation Date, hence the notation RWm

c,t-1 (resp. SRWmc,t-1 ) for each Index

Component c on Reference Period m (See Table II. below).

6.2.1.1.4. The values of Roll Weights (RW) and Signal Roll Weight (SRW) during Disrupted Valuation Days

In the following two sections, we define the procedures governing the calculation of the Index when a Disrupted Valuation Day takes place during a Roll Period. We define both the “Standard Roll” and the “Extended Roll” methodology. Disrupted Valuation Days that occur outside the Roll Period do not affect the proportion of futures contract positions maintained to hedge the dollar exposure in the Index and so no adjustment to the RW and SRW schedules is necessary. 6.2.1.1.4.1. Standard Roll methodology If a Disrupted Valuation Day occurs during the Roll Period, the RW associated with the Price Return Index on that day remains unchanged when compared to its value on the previous Index Business Day which was not a Disrupted Valuation Day in relation to the relevant Index Component. The RW on the next Index Business Day which is not a Disrupted Valuation Day is updated so that it reflects the RW which would have existed on such Index Business Day had the relevant Disrupted Valuation Days not occurred.

Unless a Disrupted Valuation Day occurs on the last day of the Roll Period, the length of the Roll Period is unaffected (See Table III. below).

And:

2/3 Day on which the Disrupted Valuation Day (DVD) takes place, and value attributed to variable

If a Disrupted Valuation Day occurs on the last day of the Roll Period, the Roll Period is extended until the transfer of positions is completed, subject to the occurrence of further Disrupted Valuation Days, provided that if the Roll Period continues until the Last Possible Roll Date (as defined in paragraph 6.2.1.2), and the Last Possible Roll Date is also a Disrupted Valuation Day, the Index Sponsor may determine, in good faith and in a reasonable commercial manner, the Index Component Level (IC Level) for the relevant Index Component (See Table IV. below).

6 Extended Roll day as part of the Roll Extension procedure

In the absence of a Disrupted Valuation Days on the following Index Business Day for the relevant Index Component, the Roll continues as originally specified. If the Roll Period continues until the Last Possible Roll Date, and a Disrupted Valuation Day occurs on the Last Possible Roll Date, the Index Sponsor may determine, in good faith and in a reasonable commercial manner, the Index Component Level (IC Level) for the relevant Index Component. 6.2.1.2. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date To facilitate the notations and calculations, we further define the following notions: The Calculation Date: any Index Business Day for which an Index Closing Level is published, The Static Data Calculation Date (SDCD): an Index Business Day on or prior to the start of the


The Calculation Period, in respect of a Static Data Calculation Date, the period from and including such Static Data Calculation Date, to but excluding the immediately following Static Data Calculation Date,

The Reference Period: in respect of a Calculation Date t, the period (denoted as m, and as specified in the relevant Index Parameters) during which the Static Data calculated on the Static Data Calculation Date falling on or immediately prior to such Calculation Date t applies,

The Last Possible Roll Date, in respect of a Calculation Period, the last Index Business Day of such Calculation Period.

6.2.1.3. The Index Component (IC) and Index Component Level (ICL) An Index Component is defined as a member of the Investment Universe which is either a designated Futures or Forward Contract defined by Section A.4. Universe of Index Components, and/or an Excess Return Index as supported by the Section 6.1. Long-Only Forward/Futures based calculation methodology, and/or 6.2. Index of Indices calculation methodology. The Index Component Level (ICLm) is the official closing price of such instrument for a relevant Calculation Date t for a Reference Period m. The Price or Level is expressed in the Reference Currency of the Index such that all Index Components Levels are expressed in the same common Currency.

6.3. Generic Basket of Assets calculation methodology In this section we introduce the Generic Basket of Assets Calculation Engine. This engine is generic in that it allows, in the same Index, the combination of long and/or short positions on either Futures or Forwards and/or Excess Return Indices supported by the methodology described in Section 6.1. Long-Only Forward/Futures based calculation methodology, Section A.6.2. Index of Indices calculation methodology and/or this Section A.6.3 Generic Basket of Assets calculation methodology. 6.3.1. Basic definitions 6.3.1.1. The Roll Period

The Roll Period represents the period from and including the First Roll Date (FRD) to and including Last Roll Date (LRD). During the Roll Period, the Index transfers positions from the Index Component (IC) defined for the previous Reference Period (denoted as m-1), to the IC defined for the current Reference Period (denoted as m) (as described in further detail in Section 6.3.1.2. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date). Both the Start and End of the Roll Period are defined in term of the number of Index Business Days from the Static Data Calculation Date of the relevant Calculation Period. For example, [+0(m)/+2(m)] means that the roll starts on the 1st Index Business Day and ends on the 3rd Index Business Day of the Calculation Period. The Price Index will therefore roll from the 1st to the 3rd Index Business Day, and the Excess Return Index will roll with a lag of one Index Business Day, from the 2nd to the 4th Index Business Day. 6.3.1.1.1. The Static Data Calculation Date (SDCD)

We define the Static Data Calculation Date (SDCD) as the date, specified in the relevant Index Parameters, on which the Static Data are calculated for the Reference Period m. For indices calculated under the Generic Basket of Assets Calculation Engine, on the Static Data Calculation Date we calculate the Unit Weights (UW) according to the particular specifications as detailed in the relevant Index Parameters. 6.3.1.1.2. The definition of Roll Weights (RW) for the Price Return Index

We define the Roll Period as a range of Index Business Days over which the transfer of positions defined for the Reference Period m-1 to the Reference Period m takes place. The Roll Rate (RR) is the frequency at which positions are transferred over the Roll Period. For example, if the Roll Period was defined as the 1st to the 3rd Index Business Day of the Calculation Period, the Price Return Index starts to reference the Static Data defined for the relevant Reference Period on the 1st Index Business Day of the Calculation Period.

The Roll Period for a given Index is defined in the relevant Index Parameters relating to the Index.

6.3.1.1.3. The definition of Index Roll Weights (RW) for the Excess Return Index

In order to mitigate the effect of Disrupted Valuation Days occurring during the Roll Period and prevent a discontinuity from affecting the Excess Return Index, the Roll Period of the Excess Return Index is delayed by one Index Business Day compared to the Roll Period of the Price Return Index, i.e. the values taken by RWm

c,t on a Calculation Date are equal to the Roll Weight used by the Price Return Index on the immediately preceding Calculation Date, hence the notation RWm

c,t-1 for each Index Component c on Reference Period m (See Table II. below).

RR 0 0 0 0 0 1/3 1/3 1/3 0 0


6.3.1.1.4. The values of Roll Weights (RW) during Disrupted Valuation Days.

In the following two sections, we define the procedures governing the calculation of the Index when a Disrupted Valuation Day takes place during a Roll Period. We define both the “Standard Roll” and the “Extended Roll” methodology. Disrupted Valuation Days that occur outside the Roll Period do not affect the proportion or futures contract positions maintained to hedge the dollar exposure in the Index and so no adjustment to the IRW and SRW schedules is necessary. 6.3.1.1.4.1. Standard Roll methodology If a Disrupted Valuation Day occurs during the Roll Period, the IRW associated with the Price Return Index on that day remains unchanged when compared to its value on the previous Index Business Day which was not a Disrupted Valuation Day in relation to the relevant Index Component. The IRW on the next Index Business Day which is not a Disrupted Valuation Day is updated so that it reflects the IRW which would have existed on such Index Business Day had the relevant Disrupted Valuation Days not occurred. Unless a Disrupted Valuation Day occurs on the last day of the Roll Period (the Last Roll Date), the length of the Roll Period is unaffected. (See Table III. below).

And:




If a Disrupted Valuation Day occurs on the last day of the Roll Period, its length is extended until the transfer of positions is completed subject to the occurrence of further Disrupted Valuation Days, provided that if the Roll Period continues until the Last Possible Roll Date (as defined in paragraph 6.3.1.2), and a the Last Possible Roll Date is also a Disrupted Valuation Day, the Index Sponsor may determine, in good faith and in a reasonable commercial manner, the Index Component Level (IC Level) for the relevant Index Component (See Table IV. below).

6 Extended Roll day as part of the Roll Extension procedure

In the absence of a Disrupted Valuation Days on the following Index Business Day for the relevant Index Component, the Roll continues as originally specified. If the Roll Period continues until the Last Possible Roll Date, and a Disrupted Valuation Day occurs on the Last Possible Roll Date, the Index Sponsor may determine, in good faith and in a reasonable commercial manner, the Index Component Level (IC Level) for the relevant Index Component. 6.3.1.1.5. Impact of Disruptions Events and Market Emergency on Basket of Composite Indices Accurately capturing the economic effects of Disruptions Events and Market Emergency on a Basket of Composite Indices requires amendments to the Disruptions methodology. To be able to isolate the effect of a Disruption Event and Market Emergency, the Composite Indices are decomposed into their underlying futures components, effectively converting the Basket of Composite Indices into a Basket of futures contracts. The basket composition of disrupted futures contracts remain at their previous index business day’s value (to reflect the economic restriction of the Disruption Event or Market Emergency, as the case may be), while the basket composition of undisrupted futures contracts are evaluated in accordance with the rules outlined in sections 6.3.1.1.4.1. and 6.3.1.1.4.2 under the assumption that no Disruption Event or Market Emegergency took place. Disruption of any contract of a Commodity futures curve leads to the disruption of all contracts of such a futures curve. 6.3.1.2. The Calculation Date, the Calculation Period, the Reference Period and the Static Data Calculation Date To facilitate the notations and calculations, we further define the following notions: The Calculation Date: any Index Business Day for which the Index Closing Level is published, The Static Data Calculation Date (SDCD): an Index Business Day on or prior to the start of the


The Roll Frequency, the frequency of Roll Periods expressed in number of months, or weeks. Usually occurring at monthly frequency (frequency then equal to one (1) month), the frequency can also be weekly (then for example, occurring on the same Index Business Day of the week

every consecutive week) or be expressed in multiples of weeks. The Roll frequency can also be a customized schedule of date,

The Calculation Period, in respect of a Static Data Calculation Date, the period from and including such Static Data Calculation Date, to but excluding the immediately following Static Data Calculation Date,

The Reference Period, in respect of a Calculation Date t, the period (denoted as m, and as specified in the relevant Index Parameters) during which the Static Data calculated on the Static Data Calculation Date falling on or immediately prior to such Calculation Date t applies,

The Last Possible Roll Date, in respect of a Calculation Period, either (a) in respect of an Index Component which is an index, the Index Business Day immediately preceding the Static Data Calculation Date falling at the end of such Calculation Period, or (b) in respect of an Index Component which is a Futures contract, the earlier of (i) the Index Business Day prior to the expiry of the Index Component (such expiry being the last trading day of the relevant Index Pricing Instrument) and (ii) the last Index Business Day of such Calculation Period.

methodology. The Index Component Level (ICL) is the Official Price of such instrument for a relevant Calculation Date t. For an Index Component Pricing Instrument which is a Futures/Forward, the Official Price is the Settlement Price as defined by the relevant Exchange or Trading Facility. For an Index Component Pricing Instrument which is an Index, the Official Price is the Closing Price as Published by the relevant Index Sponsor. The Settlement Price or Closing Price is expressed in the Reference Currency of the Index such that all Index Components Levels are expressed in the same currency. The Investment Universe for a given version of the Index is detailed in the relevant Index Parameters. 6.3.1.4.

Calculation of the Total Return Index The Generic Basket of Assets Calculation Engine supports two distinct calculation methodologies for the Total Return Index, to reflect the differing treatment of collateral yield for non-Index Business Days: the “Daily Equivalent Rate method”, and the “Compounding method” (See Section A.6.1.4.3. Calculation of the Total Return Index). For a given Index, the Total Return Index calculation method is defined in the relevant Index Parameters. 6.3.4.3.1.

7. Correlation Process In this section, we describe the correlation process that is performed if the Correlation Process Flag, as defined in the relevant Index Parameters for an Index, is set to ‘Yes’. On each Index Business Day, the correlation (over the previous 250 Index Business Days) of each Index Component in the Index Category Monitor List (as defined in the relevant Index Parameters) with the other Index Components belonging to the same Index Category (in respect of such Index Business Day, the “250 Day Correlation”), is calculated in accordance with the following formulae:

,,

,11

where n : equals 250;

: the standard variation of the log normal returns of the Front Month Contract relating to commodity x over 250 Index Business Days;

: the standard variation of the log normal returns of the Front Month Contract relating to commodity y over 250 Index Business Days;

: the average of the log normal returns of the Front Month Contract relating to commodity x over 250 Index Business Days;

: the average of the log normal returns of the Front Month Contract relating to commodity y over 250 Index Business Days;

: the log normal return of the Front Month Contract relating to commodity x on Index Business Day i;

: the log normal return of the Front Month Contract relating to commodity y on Index Business Day i; and

Front Month Contract: in respect of a commodity and any date, the first futures contract on that commodity to expire as of such date, provided that if such date falls within the period from (and excluding) the last trading day of the first contract to expire, to (and including) the date of expiration of the first contract to expire, then the second futures contract to expire, as of such date, shall be considered to be the “Front Month Contract”.

On each Index Business Day, the percentage of 250 Day Correlations over the period of all Index Business Days in the 5 years preceding such Index Business Day that are below the 80% level is calculated. If less than 75% of the 250 Day Correlations are below the 80% level, then a “Correlation Determination” is deemed to have occurred.

Appendixes A. Index Calculation Adjustments for Index Components not quoted in the Index Base Currency A.1. For Indices designed from the Long-Only Forward / Futures based calculation methodology (see Section A.6.1.) The section is applied to Commodity Indices only, with the Base Currency for all such Indices being defined as US-Dollar. When non-US-Dollar components are introduced in the composition of an Index designed from the Long-Only Forward/Futures based calculation methodology (see Section A. 6.1.), the aggregated value of a Curve Segment is defined as the sum product of the Prices of the Index Pricing Instruments (IPI) included in a given segment converted in US dollars at the prevailing FX rate, and their associated Index Pricing Instrument Nominal Weights (IPINW).

C. The calculation of Indices with embedded Fees The Credit Suisse Index Framework - Listed Markets specifies various methodologies for the calculation of Indexes with embedded fees: The Compounding method, The Linear method, and The Transaction Cost method. The methodologies are applicable to the universe of indices which can be documented under either (i) the Credit Suisse Index Framework for Listed Markets, (ii) the Credit Suisse Index Framework for OTC FX Markets, (iii) the Credit Suisse Index Framework for OTC Interest Rate Markets, or (iv) the Credit Suisse Commodity Volatility & Risk Control Series. C.1. The Compounding method In this methodology, the Fee is a function of time and the level of the Index, and as such, the impact of the level of the Index It is said to be “path-dependent”. We have:

C.3. The Transaction Cost method (only for Indices designed from the Generic Basket of Assets calculation methodology (see Section A.6.3.)) The Transaction Cost method captures indices which include a fixed cost element in the Index Calculation on particular days only. In general, such days are characterised by a change of exposure within an Index, be it due to a change of Target Investment Weights triggered by its Index Allocation Model, or through the necessity of rolling an Underlying Commodity Index Component or Index Component of the Financial Index Universe. The following method describes both cases of an Index Component being denominated in BAS, or in a foreign CCY to BAS. When Transaction Costs are introduced in the calculation of a Basket Index designed from the Generic Basket of Assets based calculation methodology (see Section A. 6.3.), the Net Index Value Increment included in a given index is adjusted respectively. This is represented by the following formula.

D. Guidance on the Calculation of Indexes using the 6.1. Long-Only Forward/Futures based calculation methodology for variable Tenor and Dynamic positioning Indices The Framework specifies two main methodologies for the purpose of the calculation of Index adjustment variables, such as the Index Continuity Factor (ICF). Below, we propose the two methodologies, which combined with the formulas proposed in Section A.6.1.1.10, allow the calculation of virtually all market Index variations: The standard procedure: the IPIs associated with zero IPINW are kept in the Curve Segment, The projection procedure: only the IPIs with non zero IPINW are kept in the Curve Segment to

which they belong, keeping only those assets in which the Index had been investing in either m or m+1.

D.1. IPI Curve Segment construction: standard procedure Table I.A. and I.B. provide examples of calculation of ICF on a single Segment and single Component (denoted CS and C) Commodity Index, when no adjustment is made to the construction of the Curve Segment prior to the calculation of the CSV and the standard procedure is applied.
